RRC configures multiple CSI trigger states. Each trigger state corresponds to one or multiple CSI reporting. The size of the CSI request field in DCI format 0_1/0_2 is configured from 0 to 6 bits by RRC signaling, so a maximum of 63 CSI trigger states (one pending state) can be indicated.

Among them, if the resource setting includes multiple aperiodic resource settings (resource sets), one of them is Only a setting is selected, and each resource setting includes a plurality of CSI-RS resources, as shown in FIG. 3. Among them, PMI is calculated based on the CSI-RS resource used for CMR included in the resource settings related to the corresponding CSI reporting.

However, in SP-CSI based on PUSCH, similar to the aperiodic CSI reporting described above, it is activated and deactivated by DCI signaling. Under the CSI feedback architecture, RRC signaling configures multiple trigger states, up to 64 trigger states, and each trigger state corresponds to one CSI reporting setting. One activation state is activated using the CSI request field in DCI. Additionally, it is possible to have multiple SP-CSIs of PUSCH in an activated state at the same time. Unlike aperiodic CSI reporting, PMI during semi-periodic CSI reporting is calculated based on the CSI-RS resource of the one CMR closest to the DCI before the DCI trigger, and the corresponding CSI-RS resource is the CSI resource related to the DCI trigger. Included in setting.

Currently, parameters configured in the terminal by high-level signaling (RRC) or MAC-CE , N or may include a plurality of candidate values in one group, or high-level signaling (RRC) or MAC-CE may configure a set consisting of a plurality of parameters. Currently, there is no corresponding codebook parameter indication method. If the information area of DCI is added directly in a general way and used for instructions, the overhead of DCI increases.

Therefore, in this embodiment, in order to reduce the overhead of DCI, the specific steps of confirming the codebook parameters using a method related to the codebook parameters and the DCI trigger state are as follows:

Step 1: The network device configures a codebook parameter, or a combination of a plurality of parameters, including at least one or a plurality of parameters of M _v , N and M _initial to the terminal through high-level signaling (RRC) or MAC-CE. Each parameter contains X≥1 candidate values, or there are X≥1 candidate parameter groups. The network device configures the S≥1 trigger state for each CSI reporting of the terminal.

Step 2: Activate a trigger state through the CSI request field in the DCI transmitted by the network device, and the trigger state not only indicates K≥1 aperiods or semi-persistent CSI reporting based on PUSCH, but also Step 1 Indicates the value of one or more parameters, or a combination of multiple parameters.

Step 3: The terminal determines the value of the codebook parameter M _v / N / M _initial based on network device configuration and/or DCI instructions.

Step 4: The terminal calculates CRI/RI/PMI/CQI information using the indicated codebook parameters and reports it to the network through the corresponding CSI.

In this embodiment, the trigger state and codebook parameter information activated through the CSI request field in the DCI implement the joint precoding indication, that is, one trigger state not only corresponds to one or a plurality of aperiodic or semi-periodic CSI reporting. Rather, it corresponds to one or more codebooks, or a combination of multiple parameters, and allows the UE to determine the ID and codebook parameters of the corresponding CSI reporting based on the coding method.

M _v denotes the number of frequency domain basic vectors; N denotes the size of the window or set; M _initial marks the starting point of the window. The codebook parameter refers to one or more of M _v , N and M _initial , or a combination of these parameters. The network device can configure reportTriggerSize in the terminal to indicate Y trigger states.

In this embodiment, the codebook parameters corresponding to the terminal can be indicated using the above-described method under the premise of not increasing DCI overhead.

In one executable embodiment, the specific actions and confirmation methods of network devices and terminals may be as follows:

First, the network device configures a codebook parameter, or a combination of a plurality of parameters, including at least one or a plurality of parameters of M _v , N and M _initial to the terminal through high-level signaling (RRC) or MAC-CE. Each parameter contains X≥1 candidate values, or there are X≥1 candidate parameter groups. The network device configures the S≥1 trigger state for each CSI reporting of the terminal, of which S≥X must be satisfied at the same time.

After that, one trigger state is activated through the CSI request field in the DCI transmitted by the network device, and the trigger state not only indicates K = 1 aperiod or semi-persistent CSI reporting based on PUSCH, but also indicates the above-mentioned Indicates one or more parameter values among parameters, or a combination of multiple parameters among parameter combinations.

In one executable embodiment, the terminal may determine the codebook parameters based on the trigger state and candidate parameters or combinations configured by the network side, specific examples are as follows:

For Y =

When Y > Confirm.

For Y > It is confirmed that it is the m)th. This is just an example and is not limiting. It should be emphasized that the mathematical calculation formulas herein are used to illustrate one calculation relationship that satisfies Y and The relationship between Y and It is within the scope of protection of the form.

Optionally, the terminal determines that the codebook parameter corresponding to the corresponding CSI reporting is one default value of X candidate parameters or combinations configured by the network device, for example, the first of the parameters or sets.

In another feasible embodiment, the network device activates a trigger state via the CSI request field in the DCI, where the trigger state not only indicates an aperiod with K>1 or semi-persistent CSI reporting based on PUSCH. , also indicates the value of one or more parameters among the above-described parameters, or a combination of a plurality of parameters among parameter combinations. The codebook parameters corresponding to the K CSI reporting can be determined according to the previous embodiment, and the codebook parameters corresponding to the K CSIs are the same.

Optionally, the K CSIs correspond to different codebook parameters. Specifically, the terminal determines that the codebook parameter corresponding to the first CSI reporting is the nth parameter value or set among Confirm that it is a set. If n+k >X, the terminal determines that the codebook parameter corresponding to the kth CSI reporting is the mod( n+k , ) indicates the remaining operation.

Furthermore, the terminal combines the codebook parameters determined in the above-described manner with the downlink channel estimated by the CSI-RS resource of the measurement channel related to CSI reporting, calculates CSI feedback information, and reports it to the network device.

Below, we introduce a specific example in which the network device configures codebook parameters for the terminal using the above-described method and then transmits a trigger status to the terminal, making it easier for the terminal to determine the reporting method and the codebook parameters to report. Do this.

Example 1:

This embodiment mainly explains semi-persistent CSI reporting based on K=1 aperiods or PUSCH, and the case where trigger status and codebook parameters are indicated by joint coding.

The base station configures a plurality of CSI reporting information to the UE, and each trigger state corresponds to one CSI reporting. The information includes codebook parameters M _v , N , and M _initial . Among them, one group includes X=4 parameter values, which are 0, N3/4, N3/2, and N3, respectively. The base station also configures reportTriggerSize of 3 to the UE through RRC signaling. The size of the DCI area is 3 bits, and 7 trigger states can be indicated, of which trigger state 0 is reserved. Among them, the joint coding instructions of the codebook parameter and the codebook parameter M _initial are as shown in Table 1 below.

For example, the base station transmits a DCI carrying aperiodic SRS transmission to the UE, the value of the corresponding DCI area is 2, activates aperiodic CSI reporting with a trigger state of 2, and also M _initial codebook corresponding to the CSI reporting. The parameter is N3/4.

Table 1: Joint coding instructions of codebook parameters and codebook parameter M _initial

In Table 1, n/a indicates that the corresponding codebook parameter cannot be determined. As can be seen in Table 1, the terminal determines the ID of CSI reporting and the value of parameter M _initial based on the corresponding DCI information, Based on other parameters such as M _v and N configured in the network device and the channel information measured by the CSI-RS resource related to the corresponding CSI reporting, other feedback information such as CRI/RI/CQI is calculated and reported to the network device.

Example 2:

This embodiment mainly describes the case where semi-persistent CSI reporting based on K>1 aperiods or PUSCH, trigger status, and one codebook parameter set are indicated for joint coding.

The base station configures a plurality of CSI reporting information to the UE, and each trigger state corresponds to one CSI reporting. CSI information includes a set of X=4 M _v , N and M _initial , respectively {1,4,0}, {2,4,N3/4}, {3,4, N3/2}, It is {4,4, N3}. The base station also configures reportTriggerSize of 3 to the UE through RRC signaling. The size of the DCI area is 3 bits, and 7 trigger states can be indicated, of which trigger state 0 is reserved. Among them, the joint coding instructions for the codebook parameters and the set of codebook parameters {M _v ,N,M _initial } are as shown in Table 2 below.

For example, the base station transmits a DCI carrying aperiodic SRS transmission to the UE, the value of the corresponding DCI area is 23, activates aperiodic CSI reporting with a trigger state of 2, and also activates aperiodic CSI reporting corresponding to the CSI reporting. Codebook parameters are {3,4, N3/2}.

Table 2: Joint coding instructions for codebook parameters and codebook parameter M _initial

As shown in Table 2 above, the terminal uses the corresponding DCI information to determine the ID and codebook parameters of CSI reporting, M _v = 3, N = 4, and M _initial = N3/2, and configures the network device. Based on other parameters and channel information measured by CSI-RS resources related to the CSI reporting, other feedback information such as CRI/RI/CQI is calculated and reported to the network device. In particular, if the value of the DCI area is m=5, the codebook parameter set corresponding to the corresponding CSI reporting is mX=1, that is, the set {1,4,0}.

The processing behavior of the UE is as described above and is not described here.

Example 3:

CSI information includes codebook parameters M _v , N , and M _initial . Among them, one group includes X=4 parameter values, which are 0, N3/4, N3/2, and N3, respectively. The base station also configures reportTriggerSize of 3 to the UE through RRC signaling. The size of the DCI area is 3 bits, and 7 trigger states can be indicated, of which trigger state 0 is reserved. Among them, the joint coding instructions of the codebook parameter and the codebook parameter M _initial are as shown in Table 3 below.

For example, the base station transmits a DCI carrying aperiodic SRS transmission to the UE, the value of the corresponding DCI area is 2, activates aperiodic CSI reporting with a trigger state of 2, and also M _initial codebook corresponding to the CSI reporting. The parameter is N3/4.

The terminal uses the corresponding DCI information to determine the value of the ID and codebook parameter M _initial corresponding to these two CSI reporting, and other parameters such as M _v and N configured in the network device and the CSI-related to these two CSI reporting. Based on the channel information measured by the RS resource, other feedback information such as corresponding CRI/RI/CQI is calculated and reported to the network.

In this embodiment, the trigger state indicated by the DCI request field not only indicates which or which aperiodic or semi-persistent PUSCH-based CSI is reported, but also indicates that the port is configured to use one or a plurality of codebook parameters of the codebook, or a plurality of codebook parameters.
